CHURN.

SPECIFICATION forming part of Letters Patent No. 665,045, dated January 1, 1901.

Application filed June 27, 1900.

T0 otZZ whom it may concern.-

Be it known that we, WILLIAM L. ALLE- GREE and WILLIAM H. ALBERT, citizens of the United States, residing at Upland, in the county of Grant and State of Indiana, have invented new and useful Improvements in Churns, of which the followingisa specification.

This invention relates to new and useful improvements in churns, and its primary object is to provide spring-power of novel construction, whereby a reciprocating motion may be imparted to the churn-dasher.

A further object is to provide a novel governor whereby the speed of the device may be regulated and to employ peculiar means for winding the spring of-the mechanism.

To these ends the invention consists in the novel construction and combination of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings, showing the preferred form of our invention, and in which- Figure 1 is a side elevation of the mechanism, showing the churn in section. Fig. 2 is a front elevation of the mechanism, showing the means for winding the spring thereof. Fig. 3 is a section on line to a: of Fig. 1.

Referring to the figures of the drawings by numerals of reference, 1 is the base upon which is mounted the churn 2. This churn is provided with a removable cover 3, having openings 4 therein for the reception of pins 5, which extend upward from the perforated disk 6, which is vertically movable within the dasher. This cover 3 has an extension 7, from which extends an eyelet or ring 8, adapted to serve as a guide for the stem 9 of the dasher 10. The dasher is secured at its upper end to a pitman 11, the opposite end of which engages a wrist-pin 12, projecting from a disk 13. This disk is mounted at one end of a shaft 14, which is supported within a frame 15 of suitable construction. This frame is mounted upon the base 1 adjacent to the churn. A pulley 16 is secured to the shaft 14 and has a groove within its periphery which receives an elastic band or belt 17. This belt extends around a larger pulley 18, mounted upon a shaft 19, journaled in the frame 15 at points below the shaft 14, hereinbefore referred to. This shaft 19 receives Serial No. 21,816. (No model.)

motion through gears 20, 21, 22, and 23 from a shaft 24, upon which is mounted a bandspring 25. This spring is secured to the gear 23 in the usual manner-4. a, by means of a pawl and ratchet, (not shown)and the outer end of the spring is secured toa fixed pin 26, as shown. The shaft 24 extends through the frame l5and is provided at its end with a ratchet-wheel 27. A lever 28 is loosely mounted upon the shaft ata point between the frame 15 and the said ratchet and may be of any desired length, the same being preferably tubular at its free end for the reception of a suitable handle. (Not shown.) A pawl 29 is pivoted to the lever at a point near the end thereof and is adapted to be held normally in engagement with the ratchet wheel by means of a bowed spring 30, which is secured to the lever, as shown. A catch 31 is pivoted to this pawl near its outer end and is adapted to be brought into engagement with a notch 32, formed in the upper end of-the lever. When this catch is in such position, the pawl will be held out of engagement with the ratchet and the same, together with the shaft, is free to revolve without carrying the lever 28 therewith. A gear 33 is secured to the upper shaft 14 within the frame and meshes with a small gear 34. Spring-bands 35 extend laterally from this gear, and the free ends thereof are secured to shoes 37, which are mounted within a drum 38, secured to the opposite side of the frame 15. These shoes are of such shape as to fit snugly against the inner surface of the drum when bearing thereagainst. A cross-strip 39 is secured within the frame at a point above the shaft 14, and loosely mounted upon this strip is a catch 40, preferably formed of a single strip of spring metal and having a toe 41 at the lower end thereof. This toe is adapted to normally engage a small gear 42, which is mounted upon the shaft 14. It is obvious that when said gear is in engagement with the toe the operation of the mechanism will be prevented, but that the catch can be readily removed from engagement therewith by simply swinging the same upward upon the strip 39.

When it is desired to operate the churndasher, the lever 28 is drawn upward, and it is obvious that the pawl 29 thereon will engage the ratchet and turn the same therewith.

When the motion of the lever is reversed, said pawl will slip over the teeth of the ratchet; but it is obvious that when the motion thereof is again reversed the pawl will be thrown into engagement with said teeth by the spring 80. By this operation the spring 25 may be readily wound upon the shaft 24. The catch 40 is then thrown out of engagement with the gear 42 and motion will be imparted from the shaft 24 to the shaft 14 through the gears 23, 22, 21, and 20 and the pulleys l8 and 16 and the belt 17. The revolution of the shaft 14 will, as is obvious, cause the dasher 10 to be rapidly reciprooated up and down within the churn. It will be understood that as the shaft 14 revolves motion will be imparted therefrom to the small gear 34, which is mounted thereabove. As this gear will be revolved at high speed the spring-bands extending therefrom will be thrown outward by centrifugal force, pressing the shoes 37 thereon firmly against the inner surface of the drum 38. This will obviously retard the movement of the mechanism, preventing the same from moving beyond the desired speed.

I11 the foregoing description We have shown the preferred form of our invention; but we do not limit ourselves thereto,as we are aware that modifications may be made therein with out departing from the spirit or sacrificing any of the advantages thereof, and we there'- fore reserve to ourselves the right to make such changes as fairly fall within the scope of our invention.

Having thus described the invention, what is claimed, and desired to be secured by Letters Patent, is-

The combination with a frame having a train of gears therein; of a spring-controlled shaft to one of said gears, a lever loosely mounted upon said shaft, a ratchet secured to the shaft, a pawl pivoted to the lever and normally engaging the ratchet, and a catch pivoted to the pawl and adapted to engage a notch within the end of the lever and retain said pawl out of engagement with its ratchet, whereby the spring-controlled shaft may revolve without turning the lever therewith.

In testimony whereof we aflix our signatures in presence of two witnesses.

WILLIAM L. ALLEGREE. WILLIAM H. ALBERT.
